How this service works
Live crypto and stock market console: OwlView charts, TBO breakout signals, order books from 34 exchanges, ETF flows, funding, liquidations and Fed odds.
Output
A JSON object containing the coin ticker plus two arrays: 'bids' and 'asks'. Each entry includes the price (in the coin's native quote currency), the USD size at that level, and the exchange/venue name (e.g. Binance, OKX) — aggregated across up to 34 exchanges.
Example use cases
Pre-trade market depth check
“Before I put in a large ETH buy, can you pull the current order book for ETH so I can see where the big ask walls are and which exchanges have the best prices?”
Cross-exchange arbitrage scouting
“Check the live order book for BTC across exchanges — I want to see if there's a meaningful spread between the best bid on one venue and the best ask on another.”
Crypto liquidity monitoring for a bot
“Every minute, fetch the order book for SOL and tell me if the total USD size on the bid side drops below $10 million — I'm watching for a liquidity squeeze.”
Technical details
Endpoint
GEThttps://owlchart.com/api/x402/orderbook?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-exchange aggregated order book depth for a cryptocurrency — especially when comparing liquidity across venues like Binance and OKX simultaneously. Prefer it over single-exchange APIs when you want a consolidated market microstructure view. It is ideal for pre-trade analysis, arbitrage detection, and liquidity monitoring at $0.03 per call.
Side effects
- Missing or invalid 'coin' query parameter returns an error — must be a valid ticker like ETH or BTC
- Unknown or unsupported ticker symbols may return empty order book arrays or an error
- Payment failure (x402 USDC payment not processed) results in a 402 response before data is returned
- Rate limits or upstream exchange connectivity issues may cause stale or incomplete data
